The outbreak of COVID-19 directly affected the government，enterprises，organizations and individuals，and also brought great pressure to the Chinese society and even the world economy，which posed more severe challenges to the high-quality development of enterprises. In the context of the technological revolution and the rapid development of the mobile Internet，the influence of social media such as Micro-blog is growing，which also creates opportunities for enterprises to achieve high-quality development through innovation. In this environment，Shanxi’s time-honored enterprises are also experiencing the challenges of the new crisis and need to pay more attention to and build online marketing channels such as Micro-blog marketing. According to the statistics，it is found that the application of using Micro-blog marketing by Shanxi time-honored enterprises is not high，the interaction is not strong and the influence is not enough. Therefore，enterprises should make full use of social media such as Micro-blog to promote digital connection. The enterprises should enhance content interaction to improve the effect of online marketing. The enterprises should improve the quality of management in an all-round way and achieve high-quality development through innovation.
